Adaptive Bandwidth Detection

Aug 09, 2017

This feature is applicable to networks with VSAT, LOS, Microwave, 3G/4G/LTE WAN Links, for which the available bandwidth varies based on weather and atmosphere conditions, location, and line of site obstructions. It allows the NetScaler SD-WAN appliances to adjust the bandwidth rate on the WAN Link dynamically based on a defined bandwidth range (minimum and maximum WAN link rate) to use the maximum amount of available bandwidth without marking the paths BAD.

  • Greater bandwidth reliability (Over VSAT, Microwave, 3G/4G, and LTE)
  • Greater predictability of adaptive bandwidth over user configured settings
